Should I be doing developmental activities with my baby at 3 weeks? I have anxiety thinking im not doing enough in that regard. He obviously pretty much only sleeps, eats, cries, cuddles. But the times that he is awake, should I be doing something to give him more stimulation?

I always said I'd start reading him books as a newborn but I miss judged how hard the newborn stage would be and am lucky to get any sleep and time for myself. Idk i just feel like i should be doing more :/
